Transmissions modified to shift without using the clutch usually dont shift well using the clutch. They usually have
no sychronizer rings and are meant to only be shifted at maximum rpm (with a slight lift of the gas pedal so you can pull the shifter) using all your strength to jam the trans into the next gear. If you normally drive like that, you might want that transmission. If you aren't going to put it into a full out drag race car, you might want to pass.
